Hi Everybady!
Raise your hand if you get or once got an error when crashing in UT (using OGL or D3D) involving the "GameEngine::Tick->Tick" error message. I'm currently facing this problem after 5-15 minuts of play, using opengl (d3d is significantly slower and i realize ogl is not officially supported in UT). I used to think the problem was unstable ram, but after some tests now I dont know. Thanks for sounding off...
